Description
BSP 53615A WO (engi) 17t3-Cyano-19-nor-androst-4-ene derivative, its use and medicaments comprising the derivative Description:
The invention relates to certain 17R-cyano-19-nor-androst-4-ene derivatives, their use and to medicaments comprising the derivatives and having gestagenic action, for example for the treatment of pre-, peri- and postmenopausal symptoms and of premenstrual symptoms.
From the literature, compounds having gestagenic, antimineralcorticoid, antian-drogenic oder antioestrogenic action based on a steroid structure are known, which are derived, for example, from 19-nor-androst-4-en-3-one or a derivative thereof (the numbering of the steroid structure can be taken, for example, from Fresenius/Gorlitzer 3rd ed. 1991 "Organisch-chemische Nomenklatur" [Organic chemical nomenclature] pp. 60 ff.).
Thus, WO 2006072467 Al describes the compound 6[3,7[i-15[i,16R-dimethylene-3-oxo-17-pregn-4-ene-21,17(3-carbolactone (drospirenone) having gestagenic action, which has been used, for example, in an oral contraceptive and a preparation for the treatment of postmenopausal symptoms. On account of its comparatively low affinity for the gestagen receptor and its comparatively high ovulation-inhibiting dose, drospirenone is contained in the contraceptive, however, in the relatively high daily dose of 3 mg. Drospirenone is moreover distinguished in that, in addition to the gestagenic action, it has aidosterone-antagonistic (antimineralcorticoid) and antiandrogenic action. These two properties make drospirenone very similar in its pharmacological profile to the natural gestagen progesterone which, however, unlike drospirenone is not adequately bioavailable orally. In order to lower the dose to be administered, in WO 2006072467 Al an 18-methyl-1 9-nor-1 7-pregn-4-ene-21,17-carbolactone and pharmaceutical preparations comprising this are further proposed which have a higher gestagenic potency than drospirenone.
BSP 53615A WO (engi) In addition, for example, US-A 3,705,179 discloses steroids which have antiandrogenic activity and are suitable for the treatment of illnesses which are connected with androgens.
In DE 22 26 552 B2, further 17-cyano-19-nor-androst-4-en-3-one compounds are described which show progestomimetic, antiandrogenic and antioestrogenic actions having exogenous character.
The object of the present invention is to make available compounds which have strong binding to the gestagen receptor. Moreover, the compounds should preferably also have an antimineralcorticoid action.
This object was achieved by the novel 17R-nor-cyano-19-androst-4-ene derivatives according to Claim 1, the use of the novel derivatives according to Claim 11, and a medicament comprising at least one novel derivative according to Claim 13.
Advantageous embodiments of the invention are indicated in the subclaims.
The present invention accordingly relates to a 17(3-cyano-19-nor-androst-4-ene derivative having the general chemical formula I

4 R6a R6b (1) where BSP 53615A WO (engl) Z is selected from the group comprising 0, two hydrogeri.atoms, NOR
and NNHSO2R, in which R is hydrogen or C1-C4-alkyl, R4 is hydrogen or halogen, furthermore either:
R6a, R6b together form methylene or 1,2-ethanediyl or Rsa is hydrogen and Rsb is selected from the group comprising hydrogen, methyl and hydroxymethylene, and R' is selected from the group comprising hydrogen, C1-C4-alkyl, C2-C3-alkenyl and cycfopropyl, or:
R6a is hydrogen and Rsb and R'together form methylene or are omitted with formation of a double bond between C6 and C7 R9, R10 are hydrogen or are omitted with formation of a double bond between C9 and C10 R15 R16 are hydrogen or together form methylene, R17 is selected from the group comprising hydrogen, C1-C4-alkyl and allyi, where at least one of the substituents R4, R6a, Rsb R' R15, R16 and R17 is unequal to hydrogen or R6b and R' are omitted with formation of a double bond between C6 and C7, and its solvates, hydrates, stereoisomers, diastereomers, enantiomers and salts.
The numbering of the C ring system of the novel derivative of the general chemical formula I customarily follows the numbering of a steroid ring system, described, for example, in Fresenius, loc. cit. The numbering of the radicals indicated in the claims analogously corresponds to their bonding position to the C ring system of the derivative. For instance, the radical R4 bonds to the C4-position of the novel derivative.
The invention relates to certain 17R-cyano-19-nor-androst-4-ene derivatives, their use and to medicaments comprising the derivatives and having gestagenic action, for example for the treatment of pre-, peri- and postmenopausal symptoms and of premenstrual symptoms.

BSP 53615A WO (engi) In addition, for example, US-A 3,705,179 discloses steroids which have antiandrogenic activity and are suitable for the treatment of illnesses which are connected with androgens.
In DE 22 26 552 B2, further 17-cyano-19-nor-androst-4-en-3-one compounds are described which show progestomimetic, antiandrogenic and antioestrogenic actions having exogenous character.
The object of the present invention is to make available compounds which have strong binding to the gestagen receptor. Moreover, the compounds should preferably also have an antimineralcorticoid action.
This object was achieved by the novel 17R-nor-cyano-19-androst-4-ene derivatives according to Claim 1, the use of the novel derivatives according to Claim 11, and a medicament comprising at least one novel derivative according to Claim 13.
Advantageous embodiments of the invention are indicated in the subclaims.
The present invention accordingly relates to a 17(3-cyano-19-nor-androst-4-ene derivative having the general chemical formula I

4 R6a R6b (1) where BSP 53615A WO (engl) Z is selected from the group comprising 0, two hydrogeri.atoms, NOR
and NNHSO2R, in which R is hydrogen or C1-C4-alkyl, R4 is hydrogen or halogen, furthermore either:
R6a, R6b together form methylene or 1,2-ethanediyl or Rsa is hydrogen and Rsb is selected from the group comprising hydrogen, methyl and hydroxymethylene, and R' is selected from the group comprising hydrogen, C1-C4-alkyl, C2-C3-alkenyl and cycfopropyl, or:
R6a is hydrogen and Rsb and R'together form methylene or are omitted with formation of a double bond between C6 and C7 R9, R10 are hydrogen or are omitted with formation of a double bond between C9 and C10 R15 R16 are hydrogen or together form methylene, R17 is selected from the group comprising hydrogen, C1-C4-alkyl and allyi, where at least one of the substituents R4, R6a, Rsb R' R15, R16 and R17 is unequal to hydrogen or R6b and R' are omitted with formation of a double bond between C6 and C7, and its solvates, hydrates, stereoisomers, diastereomers, enantiomers and salts.
The numbering of the C ring system of the novel derivative of the general chemical formula I customarily follows the numbering of a steroid ring system, described, for example, in Fresenius, loc. cit. The numbering of the radicals indicated in the claims analogously corresponds to their bonding position to the C ring system of the derivative. For instance, the radical R4 bonds to the C4-position of the novel derivative.
BSP 53615A WO (engl) With respect to the groups defined for Z, the groups NOR and NNHSO2R in each case bond using a double bond via N to the C skeleton of the derivative as in =NOR
and =N-NH-SO2R. OR in NOR and NHSO2R in NNHSO2R can be in the syn or anti position.
Cl-Ca-Alkyl is in each case understood as meaning a straight-chain or branched alkyl radical, namely methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl or tert-butyl.
Particularly preferred are especially the unbranched radicals Methyl, ethyl and n-propyl. Methyl, ethyl and n-propyl are particularly preferred. Alkyl radicals bonded in the 17a position can moreover be perfluorinated , such that R" in this case can moreover be trifluoromethyl, pentafluoroethyl, n-heptafluoropropyl, isoheptafluoropropyl, n-nonafluorobutyl, isononafluorobutyl and tert-nonafluorobutyl.
C2-C3-Alkenyl is preferably to be understood as meaning vinyl or allyl.
Halogen is in each case to be understood as meaning fluorine, chlorine, bromine or iodine.
Isomers are chemical compounds having the same empirical formula, but different chemical structure. Expressly, all possible isomers and isomer mixtures (racemates) are additionally included, the 17(3-cyano position being specified in the novel derivative.
In general, constitutional isomers and stereoisomers are differentiated.
Constitutional isomers have the same empirical formula, but differ in the manner of linkage of their atoms or atomic groups. These include functional isomers, positional isomers, tautomers or valence isomers. In principle, stereoisomers have the same structure (constitution) and thus also the same empirical formula, but differ in the spatial arrangement of the atoms. In general, configurational isomers and conformational isomers are differentiated. Configurational isomers are stereoisomers which can only be converted into one another by bond breakage. These include enantiomers, diastereomers and E/Z (cis/trans) isomers. Enantiomers are stereoisomers which behave as image and mirror image to one another and have no plane of symmetry.
All stereoisomers which are not enantiomers are designated as diastereomers.
E/Z
and =N-NH-SO2R. OR in NOR and NHSO2R in NNHSO2R can be in the syn or anti position.

The 15a,16a- and the 15(3,16(3-methylene derivatives in the above list are very particularly preferred.
On account of their gestagenic activity, the novel compounds having the general chemical formula 1 can be used alone or in combination with oestrogens in medicaments for contraception.
The derivatives according to the invention are therefore suitable in particular for the production of a medicament for oral contraception and for the treatment of pre-, peri-and postmenopausal symptoms, including use in preparations for hormone replacement therapy (HRT).
Because of their favourable profile of action, the derivatives according to the invention are particularly highly suitable for the treatment of premenstrual symptoms, such as headaches, depressive disgruntlements, water retention and mastodynia.
The use of the derivatives according to the invention for the production of a medicament having gestagenic and antimineralcorticoid action is particularly preferred.
Treatment with the derivatives according to the invention preferably takes place in humans, but can also be carried out on related mammalian species, such as, for example, on dog and cats.
For the use of the derivatives according to the invention as medicaments, these are combined with at least one suitable pharmaceutically harmless additive, for example vehicle. The additive is suitable, for example, for parenteral, preferably oral, administration. It is a matter here of pharmaceutically suitable organic or inorganic BSP 53615A WO (engl) inert additive materials, such as, for example, water, gelatine, gum arabicum, lactose, starch, magnesium stearate, talc, vegetable oils, polyalkylene glycols etc.
The medicaments can be present in solid form, for example as tablets, coated tablets, suppositories, capsules, or in liquid form, for example as solutions, suspensions or emulsions. Optionally, they moreover contain excipients, such as preservatives, stabilizers, wetting agents or emulsifiers, salts for changing the osmotic pressure or buffers. For parenteral administration, oily solutions, such as, for example, solutions in sesame oil, castor oil and cottonseed oil, are in particular suitable. To increase the solubility, solubilizers, such as, for example, benzyl benzoate or benzyl alcohol, can be added. It is also possible to incorporate the derivatives according to the invention into a transdermal system and thus to administer it transdermally. For oral administration, tablets, coated tablets, capsules, pills, suspensions or solutions are in particular suitable.
The dose of the derivatives according to the invention in contraception preparations should be 0.01 to 10 mg per day. The daily dose in the case of the treatment of premenstrual symptoms is approximately 0.1 to 20 mg. The gestagenic derivatives according to the invention are preferably administered orally in contraception preparations and in the medicaments for the treatment of premenstrual symptoms.
The daily dose is preferably administered as a single dose.
The gestagenic and oestrogenic active substance components are preferably administered together orally in contraception preparations. The daily dose is preferably administered as a single dose.
Possible oestrogens are synthetic oestrogens, preferably ethinylestradiol, but also mestranol.
The oestrogen is administered in a daily amount which corresponds to that of 0.01 to 0.04 mg of ethinylestradiol.
Oestrogens, of course, are primarily used as oestrogens in the medicaments for the treatment of pre-, peri- and postmenopausal symptoms and for hormone replacement BSP 53615A WO (engi) therapy, especially oestradiol or its esters, for example oestradiol valerate, or alternatively conjugated oestrogens (CEEs = Conjugated Equine Estrogens).
If the preparation of the starting compounds is not described here, these are known to the person skilled in the art or can be prepared analogously to known compounds or processes described here. The isomer mixtures can be separated into the enantiomers, E/Z isomers or epimers by customary methods, such as, for example, crystallization, chromatography or salt formation.
The derivatives according to the invention having the general chemical formula I are prepared as described below.
Suitable starting materials for the 173-cyano-19 nor-androst-4-en-3-one derivatives described here are various steroidal starting materials, such as, for example, 19-nor-and rost-4-en e-3,1 7-dione, or alternatively the partially reduced analogues.
Microbiologically, for example, 15a-hydroxy-19-nor-androst-4-ene-3,17-dione is accessible, which opens up access to 15f3,16R-methylenated 17-cyanosteroids, for this see examples in the experimental section. 15a,16a-Methylenated precursors which are suitable for the synthesis of the corresponding 17-cyanosteroids are likewise known, e.g. 1713-hydroxy-15a,16a-methylene-19-nor-androst-4-en-3-one in DE-A 22 07 421 (1973). Access to 17(3-cyano-19-nor-androst-4-en-3-one is described in DE-A 22 26 552.
It is obvious to the person skilled in the art that in the descriptions of the synthetic transformations it is always provided for other functional groups optionally present on the steroid ring system to be protected in suitable form.
The introduction of a nitrile into position 17 (C17) of the steroid ring system can be carried out in a variety of ways. Both single-stage processes and multistage variants are possible here. Methods are preferred here which finally mean the replacement of an oxygen function by cyanide. Many possible process variants are described in Science of Synthesis Houben-Weyl Methods of Molecular Transformations Category 3 Volume 19 pp. 197-213 (2004 Georg Thieme Verlag Stuttgart, New York) and in BSP 53615A WO (engl) Houben-Weyl Methoden der organischen Chemie [Houben-Weyl Methods of organic chemistry] Volume E5 Part 2 pp. 1318-1527 (1985 Georg Thieme Veriag Stuttgart, New York).
A single-stage process which suggests itself is, for example, the direct reductive replacement of a carbonyl oxygen atom by a cyano group. For this, a 17-ketosteroid is reacted with tosylmethyl isocyanide in suitable solvents, such as, for example, dimethoxyethane, dimethyl sulphoxide, ethers, alcohols or alternatively their mixtures, using suitable bases, such as, for example, alkali metal alkoxides, alkali metal hydrides, potassium hexamethyldisilazide, or alternatively alkali metal amides, such as, for example, lithium diisopropylamide, in a temperature range from 0 C to 100 C. 17-Epimer mixtures which may be formed can be separated by chromatography, fractional crystallization or using a combination of these methods.
The SN2-type replacement of a suitable leaving group in position 17, such as, for example, of a halide (preferably iodine or bromine), or alternatively of a sulphonic acid ester of a 17-alcohol, by cyanide is also possible. Cyanide sources used are preferably inorganic cyanides, such as lithium cyanide, sodium cyanide and potassium cyanide.
The following may be mentioned as examples of multistage variants of nitrile introduction: a 17-ketone is converted by means of a Wittig olefination to the corresponding 17-exomethylene compound, which after hydroboration and oxidation to the aidehyde can be reacted to give the corresponding 17-carbaidehyde oxime.
Dehydration of the oxime then leads to the 17-nitrile.
The introduction of the nitrile can be carried out both at the beginning of a synthesis sequence and also at any desired later point in time, provided that further functional groups which may be present are protected in a suitable manner.
The 17-cyano compounds can be optionally alkylated, which leads to stereochemically homogeneous 17(3-cyano-17a-substituted derivatives. For this, the 17-cyanosteroid is deprotonated in a suitable solvent, such as, for example, ethers, for example tetrahydrofuran. Various bases can be used here, for example an alkali BSP 53615A WO (engi) metal amide, such as lithium diisopropylamide. After addition of an alkylating agent, such as, for example, of an alkyl or alkenyl halide, and work-up, the 1713-cyano-17a-substituted derivatives are then obtained.
By way of example, the further synthetic procedure may be illustrated with the aid of the following synthesis scheme, the compound 2 (DE-A 22 26 552 (1972)) already described being mentioned as a starting material:

The introduction of a 6,7-double bond is carried out by means of bromination of the 3,5-dienol ether 5 and subsequent elimination of hydrogen bromide (see, for example, J. Fried, J.A. Edwards, Organic Reactions in Steroid Chemistry, von Nostrand Reinhold Company 1972, pp. 265-374).
The introduction of a substituent R4 can be achieved, for example, starting from a compound of the formula 2, by epoxidation of the 4,5-double bond with hydrogen BSP 53615A WO (engl) peroxide under alkaline conditions and reaction of the resulting epoxides in a suitable solvent with acids having the general chemical formula H-R4, where R4 can be a halogen atom or a pseudohalogen, or by reacting with catalytic amounts of mineral acid and optionally reacting the 4-bromo compounds obtained having the general chemical formula 1(where R4 = bromine) with methyl 2,2-difluoro-2-(fluorosulphonyl)-acetate in dimethylformamide in the presence of copper(I) iodide.
The dienol ether bromination of compound 5 can be carried out, for example, analogously to the procedure of Steroids 1, 233 (1963). The elimination of hydrogen bromide is possible by heating the 6-bromo compound with basic reagents, such as, for example, LiBr or Li2CO3, in aprotic solvents, such as dimethylformamide, at temperatures from 50 C to 120 C or else by heating the 6-bromo compounds in a solvent, such as codlidirie or lutidine, to give compound 6.
Compound 7 is converted by methenylation of the 6,7-double bond according to known processes, for example using dimethylsulphoxonium methylide (see, for example, DE-A 11 83 500, DE-A 29 22 500, EP-A 0 019 690, US-A 4,291,029; J.
Am. Chem. Soc. 84, 867 (1962)) to a compound 8, a mixture of the a- and R-isomers being obtained, which can be separated into the individual isomers, for example, by chromatography.
Compounds of the type 7 can be obtained as described in the examples or analogously to these procedures using reagents analogous to those described there.
The synthesis of the spirocyclic compound 12 starts from 2, which is first converted to a 3-amino-3,5-diene derivative 9. By reaction with formalin in alcoholic solution, the 6-hydroxymethylene derivative 10 is obtained. After conversion of the hydroxyl group to a leaving group, such as, for example, a mesylate, tosylate (compound 11) or alternatively benzoate, compound 13 can be prepared by reaction with trimethylsulphoxonium iodide using bases, such as, for example, alkali metal hydroxides or alkali metal alkoxides, in suitable solvents, such as, for example, dimethyl sulphoxide.

K. Annen, H. Hofmeister, H. Laurent and R. Wiechert, Synthesis 34 (1982)).
The 6-methylene compounds carr be used for the preparation of compounds having the general formula 1, in which R6a is equal to methyl and R6b and R7 are omitted with formation of a double bond between C6 and C7.
For this, for example, a process described in Tetrahedron 21, 1619 (1965) can be used, in which an isomerization of the double bond is achieved by warming the methylene compounds in ethanol with 5% palladium-carbon catalyst, which was pretreated either with hydrogen or by warming with a small amount of cyclohexene.
The isomerization can also be carried out using a catalyst which was not pretreated, if a small amount of cyclohexene was added to the reaction mixture. The occurrence of small amounts of hydrogenated products can be prevented by addition of an excess of sodium acetate.
The 6-methyl-4,6-dien-3-one derivatives, however, can also be prepared directly (see K. Annen, H. Hofmeister, H. Laurent and R. Wiechert, Lieb. Ann. 712 (1983)).
Compounds in which R6b is an a-methyl function can be prepared from the 6-methylene compounds by hydrogenation under suitable conditions. The best results (selective hydrogenation of the exo-methylene function) are achieved by transfer hydrogenation (J. Chem. Soc. 3578 (1954)). If the 6-methylene derivatives are heated in a suitable solvent, such as, for example, ethanol, in the presence of a hydride donor, such as, for example, cyclohexene, 6a-methyl derivatives are BSP 53615A WO (engl) obtained in very good yields. Small amounts of 6R-methyl compound can be isomerized by acid (Tetrahedron 1619 (1965)).
The selective preparation of 6[3-methyl compounds is also possible. For this, the 4-en-3-ones, such as, for example, compound 2, are reacted, for example, with ethylene glycol or trimethyl orthoformate in dichloromethane in the presence of catalytic amounts of an acid, e.g. p-toluenesulphonic acid, to give the corresponding 3-ketals. During this ketalization, the double bond in position 5(C5) isomerizes. A
selective epoxidation of this 5-double bond is possible, for example, by use of organic peracids, e.g. of m-chloroperbenzoic acid, in suitable solvents, such as dichloromethane. Alternatively to this, the epoxidation can also be carried out using hydrogen peroxide in the presence of, for example, hexachloroacetone or 3-nitrotrifluoroacetophenone. The 5,6a-epoxides can then be opened axially using appropriate alkylmagnesium halides or alkyllithium compounds. 5a-Hydroxy-6[3-alkyl compounds are thus obtained. The cleavage of the 3-keto protective group can be carried out with obtainment of the 5a-hydroxyl function by treating under mild acidic conditions (acetic acid or 4 N hydrochloric acid at 0 C). Basic elimination of the 5a-hydroxyl function using, for example, diluted aqueous sodium hydroxide solution affords the 3-keto-4-ene compounds having a R-6-alkyl group. Alternatively to this, ketal cleavage under more drastic conditions (aqueous hydrochloric acid or another strong acid) affords the corresponding 6a-alkyl compounds.
The compounds having the general chemical formula 1 obtained, in which Z is an oxygen atom, can be converted to their corresponding oximes (general chemical formula 1 with Z denoting NOH, where the hydroxyl group can be syn- or anti-) by reaction with hydroxylamine hydrochloride in the presence of a tertiary amine at temperatures between -20 and +40 C. Suitable tertiary bases are, for example, trimethylamine, triethylamine, pyridine, N,N-dimethylaminopyridine, 1,5-diazabicyclo[4.3.0]non-5-ene (DBN) and 1,5-diazabicyclo[5.4.0]undec-5-ene (DBU), pyridine being preferred. This applies analogously as is described in WO-A
for the preparation of corresponding 3-oxyimino derivatives of drospirenone.
The removal of the 3-oxo group for the preparation of a final product having the general chemical formula I with Z denoting two hydrogen atoms can be carried out, BSP 53615A WO (engi) for example, by reductive cleavage of a thioketal of the 3-keto compound according to the procedure indicated in DE-A 28 05 490.
The following examples serve for the more detailed illustration of the invention:
The compounds according to the invention are surprisingly distinguished by strong gestagenic activity and are strongly active in the maintenance of pregnancy test on the rat after subcutaneous administration.
Carrying out the maintenance of pregnancy test on the rat:
In pregnant rats, the removal of the corpora lutea or oophorectomy induces an abortion. By means of the exogenous administration of progestins (gestagens) in combination with a suitable dose of an oestrogen, the maintenance of pregnancy is possible. The maintenance of pregnancy test on ovarectomized rats serves for the determination of the peripheral gestagenic activity of a compound.
Rats were paired overnight during proestrus. Pairing was checked on the morning of the following day by the appraisal of a vaginal smear. The presence of the sperm was evaluated here as day 1 of a commencing pregnancy. On day 8 of the pregnancy, the animals were ovarectomized under ether anaesthesia. The treatment with test compound and exogenous oestrogen (oestrone, 5 pg/kg/day) was carried out subcutaneously once daily from day 8 to day 15 or day 21 of the pregnancy.
The first administration on day 8 was carried out two hours before oophorectomy.
Intact control animals were given exclusively vehicle.
Evaluation:
At the end of the experiment (day 15 or day 21), the animals were sacrificed under a CO2 atmosphere, and live foetuses (foetuses having a beating heart) and implantation sites (early resorptions and dead foetuses including autolysis and atrophic placentas) were counted in both uterine horns. On day 22, it was moreover possible to examine foetuses for malformations. In uteri without foetuses or implantation sites, the number of nidation sites was determined by staining with 10%
34, 2464 (1991)).

On day 22, it was moreover possible to examine foetuses for malformations. In uteri without foetuses or implantation sites, the number of nidation sites was determined by staining with 10%
BSP 53615A WO (engl) strength ammonium sulphide solution. The maintenance of pregnancy rate was calculated as the quotient of the number of living foetuses and the total number of nidation sites (both resorbed and dead foetuses and nidation sites). For certain test substances, the pregnancy-maintaining doses (ED50) indicated in Table 1 were determined. For drospirenone, this value is 3.5 mg/kg/day.
The derivatives according to the invention having the general chemical formula have a very strong gestagenic activity. It was moreover found that the derivatives according to the invention show antimineralcorticoid action in vitro. They should therefore have in vivo potassium-retaining, natriuretic (antimeralcorticoid) action.
These properties were determined using the test described below:
For the culturing of the cells used for the assay, the culture medium used was DMEM
(Dulbecco's Modified Eagle Medium: 4500 mg/mI of glucose; PAA, #E15-009) with 10% FCS (Biochrom, S0115, batch #615B), 4 mM L-glutamine, 1%
penicillin/streptomycin, 1 mg/mI of G418 and 0.5 pg/mI of puromycin.
Reporter cell lines were grown in a density of 4 x 104 cells per hollow in white, nontransparent tissue culture plates in each case having 96 hollows (PerkinElmer, #P12-106-017) and kept in 6 % DCC-FCS (activated carbon-treated serum, for the removal of interfering components contained in the serum). The compounds to be investigated were added eight days later, and the cells were incubated with the compounds for 16 hours. The experiments were carried out in triplicate. At the end of the incubation, the effector-containing medium was removed and replaced by lysis buffer. After luciferase assay substrate (promega, #E1501) had been added, the plates containing the 96 hollows were then introduced into a microplate luminometer (Pherastar, BMG labtech), and the luminescence was measured. The IC50 values were evaluated using software for the calculation of dose-activity relationships.
